FIG. 27.—Ammonifying bacteria.—1. Bacterium mycoides; X 3, 000. (Nadson.) 2. Bacterium mycoides; involution forms; X 3, 000. (Nadson.) 3. Bacterium tumescens. (Myer.) 4. Proteus vulgaris; X 3, 000.

He further found that the gelatin liquefiers have an ammonifying power nearly twice as great as the non-liquefiers. Chester found all but one of the organisms tested by him capable of producing ammonia. C. B. Lipman tested the following fifteen organisms in soils: B. mesentericus mdgatus, Ps. putida, B. mdgatus, B. megatherium, B. mycoides, B. snltilis, B. tumesccns, Sarcina lutea, B. proteus vulgaris, B. icteroides, B. ramosus, Streptothrix, sp., /'.v. jluorcscens, B. wilgarix (navy strain), and Mic, tetragenus as to their ammonifying powers of dried blood, tankage, cotton-seed.
